CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 279,763, dated June 19,1883.

I Application filed March 20, 1883. (N model.)

' of Ohio, have invented a new and Improved (Jar-Coupling, of which thefollowing is a full, clear, and exact description.

My invention consists of a cranked drum located over the coupling-pinand having the pin suspended from it, with a spring-latch to hold thepin up for selfcoupling when tripped by the approaching car, and cranksfor raising the link and setting it, the same being a simple andefficient eontrivance for self-coupling, as hereinafter fully described,

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicate corresponding parts in all the figures. I Figure 1 is a perspective view ofmy improved car-coupling. Fig. 2 is a longitudinal section of the same;and Figs. 3 and 4 are perspective views of the lifting, suspending, andtripping arm.

I arrange housings a 011 the top of the drawbar I), at each side, orthereabout, for the support of the crank-shaft c, whereon I have a drum,(1, to the periphery of which the pin 6 is connected by a chain, f, sothat the pin may be raised up out of the link and be suspended above itby turning the drum until the latch g swings under shoulder h, thecranks i of the shaft being then raised up to a horizontal position, sothat when the drum is tripped for allowing the pin to fall the weight ofthe cranks will turn the drum and prevent the fall of the pin beinghindered by them, and also so that they hang downward when the pin isdown. The latch is to be tripped, to let the pin fall when the cars cometogether, by the draw-bar of the'car to be coupled 011 pressing back thepusher j against the lower end of latch g. The spring k swings the latchforward and causes the upper end to swing under shoulder 71,when the pinis to be set. Said spring throws the pusher forward at the same time.The latch g is arranged in a'vertical position under the drum d'on apivot, Z, supported by the housings a, and the lower end of the latchextends into a recess, m, in the draw-bar, where it meets the head ofpusher j, extending fronr said recess out through a hole in the end ofthe draw-bar. The drum (1 has another shoulder, a, that rests on the endof the latch gwhen the pin is down, which, together with the weight ofthe pin and crank, prevent the drum from turning out 'of position, andthere is also another shoulder, 0, to serve as a stop by 0011- tact withbar 1, attached .to one of the housings, to prevent the drum from beingturned too far back when being raised; also to prevent it beingaccidentally turned when the pin is set.

In this example the crank-shaft is repre sented as being made in one redor shaft going entirely through the drum; but in practice I shall preferto make it in two separate parts to be inserted into the drum at eachend, and be secured by set-screws as a simple ar rangement forconstruction and application of the cranks and the drum to the housings.

It will be seen that by making the cranks t to extend the properdistance each way from the draw-bar the pin can be raised to uncoupleand set without going between the cars and being exposed to dangerthereby. I propose to arrange a cover, 1), of sheet metal over thehousings at the back part, and ahinged door, q, over the front part toexclude the snow and rain.

I have in this case represented the draw-bar as made in two parts thatmay be separated for the placing of the push-pin in position with itshead within the recess to effectually secure it, and I prefer thisarrangement, although it may be made solid with other means of securingthe pin.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the lever-latch g, of the pin-lifting drumhaving the shoulder la, whereby the pin may be held up, as described.

2. The combination, with lever-latch g, of the pin-lifting drum havingthe notch n,whereby the drum cannot turn forwardly beyond said notch, asdescribed.

' 3. The combination, with the pin-lifting drum having the shoulder 0,oilthc bar t,whereby .the drum cannot be accidentally turned I fartherback than said shoulder, as described. 4. The pin raising and settingdrum having shoulders 71, n, and 0, in combination wlth latch g and astop, t, and being mounted with.

between the two parts of a draw-bar fastened together, substantially asdescribed.

7. The combination, in a car-coupling, of a setting and tripping drum,the coupling-pinv connected to said drum by a chain, housings for thesupport of the drum, and an inclosingcover, 19, and door q of thehousings, substantially as described.
